I hunt wilderness areas here in Colorado, I would NOT skimp on a GPS or binos. I would however, lighten your shelter by about half, 5 pounds is really heavy for shelter for one.
With my heavy Eberlsestock pack, packed for 8 days, was 42-43 lbs. This coming up year, I am going to lighten my pack up by getting rid of the Eberlestock and getting a technical pack from REI or the like.
Your overall sleeping system should be no more than 6-6.5lbs.(including bag, pad, and shelter), bring lightweight food (mountain house, etc). Dont need to have multiple sets of clothes (I carry one base layer, one layer of Microtec, and a lightweight goretex outer-layer. The only thing I bring multiples of are socks and underwear). Use the Lithium AA's for your GPS, and only fire it up to mark wallows or rubs, and to find the tent in the dark.
This doesnt cover everything, I know, but I think the your biggest weight items are your backpack, sleeping/shelter system, and clothing, so thats where you concentrate on reducing some weight.
Here are some pics of my hunt last year. (If you hunt somewhere with a 2000ft elevation gain on your hike in, 5-6 miles will feel much further than you think!)
